CHAIR-GUIDE,

SP ECIPICATION forming part of Letters Patent No. 355,689, dated Januaryll, 1887.

(No model.)

To aZZ whom it may concern.-

' Be it known that I, GEORGE FELDKAMP, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and useful my improvedlocking device; Fig. 2, a plan view of the same; Fig. 3, an enlargedside view, partly in section, with the locking mechanism; Fig. 4, anenlarged external View of the locking attachment, and Fig. 5 a plan Viewof the locking attachment'detached; and Fig. 6, a perspective view ofthemet-al piece forming the hinge.

This invention relates to an improvement in lockin g attachments forchildrenshigh chairs, consisting of the guard hinged to the arm at oneside of the chair, and connecting at the opposite side with aspring-bolt, so as to be held in position beneath the arms of the chair,the said bolt having a ring at its lower end, so as to be readily openedwhile the said guard rests upon the case containing-the bolt, whichprevents it from becoming twisted or broken,

all of which will now be fully set forth.

In the accompanying drawings, A, Fig. 1, represents an ordinary childshighchair. The arm-support B is secured to the frame or seat of thechair as ordinarily constructed, and the upper end of this said supportis provided with a metal case, D, fitted thereon, for which purpose theshoulder E, at its upper end, is placed lower down than ordinarily,instead of simply resting against the lower side of the arm F. Thismetal piece D, placed on the upper end of the support B, is so disposedas to have a flange,,G,' rearwardly provided with an opening, so as tosecure it to the lower side of the arm F by means of the screw H.

This metal piece D projects forwardly from the support B, with its upperside provided with a rabbet, I, the thickness of the guard J. Thisforward part K of the metal piece D has vertical openings L, and isprovided therein with a bolt, M, projecting up through the cross-pieceM, having a ring, N, at its lower end, the upper end designed to projectsomewhat above the face of the rabbet I, forming a bolt or catch for theguard J; for which purpose a suitable opening, 0, is provided in theunder face of the guard J.

A spiral spring, P, is placed on the bolt M, and interposed between theupper and lower faces of the forwardly-projecting part K of the metalpiece D. The spiral spring P is secured to the bolt M, and to the upperpart 01" the metal piece D, and has such a tension that the normalposition of the bolt M is with its upper end projecting through and intothe rabbet I, so as to engage with the opening 0 of the guard J. The armof the chair having the guard J hinged thereto is provided with a metalpiece, D, corresponding to theone already described, except that inplace of the bolt M, extending through the forward part of the metalpiece D, a fixed lug or stud, Q, is provided on the upper face of themetal piece and extending up to the under surface of the arm F, whichreceives the end of the'guard J, and thus acts as a hinge. Ordinarilythese guards J are placed upon and hinged directly to the upper end ofthe support B,or are hinged immediately over the'arm; but, as will be n0ticed, one of the features of my device is that the forward andlaterally projecting sides of the metal piece D, in conjunction'with theunder surface of the arms F, permit of the guard J swinging aroundbeneath the arm without being liable of getting twisted or broken,

as in the ordinary guard.

In operating the device, the guard J being I hinged to one of the arms,it is simply swung around so as to come in contact with the shoulder ofthe rabbet I, where the vertical and the chair-arms F,combined with themetal piece D, fitted on the upper end of the support B, and the pivotedguard J, all substantially as and for the purpose described.

2. In a high chair,the metal piece placed on the upper end of the sidesupport, beneath the arm, having a rabbet forwardly to act as a supportfor the guard, anda vertical bolt so the piece D under the other arm,provided disposed as to engage with the recess of the guard,substantially as herein set forth.

3. A childs high chair having a guard pivoted on hinge under one arm andrecessed under the other end, combined with a metal piece under theother chair-arm, provided with a springbolt adapted to fit into saidrecess, all substantially as described.

4. In combination with the chair, the hinge piece D, having stud Q underone arm and with a spring-bolt, and the swinging guard J, 7 adapted tobe caught by the said spring-bolt, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this20th day of February, 1886, in the presence of witnesses.

GEORGE FELDKAMP.
